When Windows Mixed Reality Portal cannot be started, you can fix it by following the steps: 1. Confirm that the system meets the hardware requirements, including graphics card, USB and DisplayPort versions; 2. Restart the Mixed Reality related services and set it to automatically start; 3. Reinstall the Mixed Reality Portal application to clear corrupt files; 4. Update or reinstall the graphics card driver to ensure compatibility and stability; if it is still invalid, try system file checking or resetting the Mixed Reality settings.

Windows Mixed Reality Portal not launching can be a real pain, especially if you're ready to dive into VR but the app just won't start. The issue can come from a few different places — driver problems, software conflicts, or even a corrupted install. Here's how to actually fix it without wasting hours on trial and error.

Check Your System Requirements and Hardware Compatibility

Before diving into complicated fixes, make sure your system actually meets the requirements for Mixed Reality. It's not uncommon for people to try running it on borderline hardware and run into issues.

• Graphics card : Needs to be at least an NVIDIA GTX 960 or AMD Radeon R9 380X or better.
• USB ports : Make sure your headset is connected to a USB 3.0 port and not a 2.0 one.
• Display port : The correct version (DisplayPort 1.2 or higher) matters too.
• Mixed Reality Portal compatibility check : Run the official compatibility tool from the Microsoft Store to confirm everything's good on paper.

If your system barely meets the requirements, you might still have issues even after fixing other things.

Restart the Mixed Reality Services

Sometimes, the problem is just that the background services aren't running properly. Restarting them is a quick and effective fix that often gets overlooked.

Here's how:

• Press Win R , type services.msc , and hit Enter.
• Scroll down and find Mixed Reality Device Portal and Windows Mixed Reality Portal services.
• Right-click each one and choose Restart .
• If they're not running, start them manually.

You can also set these services to Automatic (Delayed Start) so they don't interfere with boot time but still launch reliable when needed.

Reinstall or Repair Mixed Reality Portal

If the app just won't open at all, reinstalling it can help clear out any corrupted files or missing dependencies.

• Open Settings > Apps > Apps & features .
• Scroll down and find Mixed Reality Portal .
• Click it and select Uninstall .
• Then go to the Microsoft Store and search for “Mixed Reality Portal” again.
• Install it fresh and try launching again.

If you see an error during install, check your internet connection and Windows Update — sometimes a missing system update blocks the app from installing correctly.

Update or Reinstall Graphics Drivers

A lot of Mixed Reality issues come down to graphics driver problems. If your drivers are outdated or corrupted, the app might not even launch.

• Go to your GPU manufacturer's website (NVIDIA, AMD, or Intel).
• Download and install the latest drivers for your specific model.
• Or use Device Manager to check for updates under Display adapters .

Some users have also found success by completely uninstalling their GPU drivers and letting Windows reinstall them automatically on reboot. Just be careful — this might temporarily lower your display quality until drivers are back.

If none of these steps work, you might want to try a system file check ( sfc /scannow ) or even a reset of your Windows Mixed Reality setup through the settings. But for most people, the above fixes should get the portal launching again without too much hassle.
